Nanomaterials offer new technical and commercial opportunities. However, they may also pose risks to consumers and the environment and raise concerns about occupational health and safety. An overview of the standardization in the area of nanomaterials is presented. Focus is given to the standard ISO/TS 12901-2:2014, which describes the use of a control banding approach for controlling the risks associated with occupational exposures to nano-objects and their aggregates and agglomerates greater than 100 nm. The article also presents a case study on a textile finishing company that implements two chemical finishes containing nanomaterials. A risk analysis was conducted to assess the hazards associated with workers handling nanomaterials. Control banding was applied, and measures such as appropriate ventilation and use of protective equipment are proposed to mitigate risks. In some cases, additional measures, such as a closed booth and smoke extractor, are required. The safety data sheets are a primary source of information on how to handle and care for products containing nanomaterials, but the information provided is still limited in terms of the specific hazards and risks posed by nanomaterials.
纳米材料提供了新的技术和商业机会。然而，它们也可能对消费者和环境构成风险，并引发对职业健康和安全的关注。本文概述了纳米材料领域的标准化情况。重点介绍了标准 ISO/TS 12901-2:2014，该标准描述了如何使用控制带方法来控制与职业接触纳米物体及其大于 100nm 的聚集和团聚物相关的风险。本文还介绍了一家实施两种含纳米材料的纺织品整理公司的案例研究。进行了风险分析以评估与处理纳米材料的工人相关的危害。应用了控制带方法，并提出了适当的通风和使用防护设备等措施来降低风险。在某些情况下，需要采取其他措施，例如封闭工作间和抽气装置。安全数据表是关于如何处理和护理含纳米材料产品的主要信息来源，但所提供的信息在纳米材料带来的具体危害和风险方面仍然有限。
